Description

Family kitchen air purifier
Technical field
The present invention relates to a kind of air cleaning units, more particularly, to a kind of family kitchen air purifier.
Background technology
In gastronomical process, edible oil can form 3 kinds of a kind of gaseous state, liquid and solid-state organic forms under the high temperature conditions Mixture, i.e. oil smoke.According to the difference of form, the mixture of liquid particles and solid granulates is referred to as mist of oil, these particles Being divided into can sedimented particle and inhalable particles;Gaseous parts are volatile organic compounds (VOCs), the gaseous state in family kitchen Pollutant also has burning waste gas.In oil smoke can the grain size of sedimented particle be mainly distributed between 10-400um, these particles by Interaction between the effect and particle and particle of its own gravity can be deposited to ground and other implements surfaces, will not be right Air in kitchen environment generates persistent pollution.Grain size is usually called inhalable particles, i.e. PM10 in 10um particles below, this A little particles do not allow free settling, always swim in air in kitchen environment, it can be sucked by human body, be deposited on respiratory tract, alveolar Equal positions are detrimental to health to cause disease.The grain size of particle is smaller, and the position into respiratory tract is deeper.Inhalable Particle of the diameter less than or equal to 2.5um is referred to as particulate matter in grain, i.e. PM2.5 and grain size are more than 2.5um, are less than The particle of 10um is compared, and PM2.5 is to the harm bigger of human body, and VOCs can also be formed by aerial chemical reaction PM2.5。
Present cooking fume pollutes and its has become very valued indoor environment to the Health cost effect of human body Problem.Smoke exhaust ventilator can will be generated as a kind of electric appliance of purification kitchen environment in the exhaust gas and cooking process of cooking stove burning Oil smoke take away rapidly, be discharged to outdoor, reduce the pollution to air environment in kitchen, but it is desirable to only just by smoke exhaust ventilator Exhaust gas, oil smoke and peculiar smell are thoroughly discharged it is also very difficult because always having the part of escape in aspiration procedure, and these Fail the exhaust gas being discharged, oil smoke and peculiar smell to stay in kitchen, threatens people's health, and simultaneously using smoke exhaust ventilator Original air quality in family kitchen cannot be improved.Consumer present simultaneously is stronger for the open demand of family kitchen Strong, in gastronomical process, kitchen is once open wide, although using smoke exhaust ventilator, the air environment in dining room and parlor is still It can be affected.
